Description
This application is a continuation-in-part of U.S. Pat. application Ser. No. 351,070, filed Apr. 13, 1973, now abandoned.
This invention concerns 1-arylthio-1,1-dihalomethanesulfonamides and the corresponding sulfinyl and sulfonyl derivatives corresponding to the formula ##SPC2##
Wherein R represents hydrogen, lower alkyl, lower alkoxy or halo, x represents an integer from 0 to 2, n represents an integer from 0 to 3, Y represents halo and R1 and R2 independently represent hydrogen, lower alkyl, phenyl or substituted-phenyl, or, together with the nitrogen atom, form a heterocyclic ring also containing up to one oxygen atom in the heterocycle.
In the specification and claims, "lower alkyl" and "lower alkoxy" represent 1, to 2, to 3, to 4, carbon atom straight chain alkyl groups, such as, for example, methyl, ethyl, n-propyl or n-butyl, or a corresponding alkoxy group, respectively; the term "halo" with reference to R represents fluoro, chloro or bromo and with reference to Y represents chloro or bromo; and the term "substituted-phenyl" represents phenyl having lower alkyl, lower alkoxy, chloro or bromo substitution.
The compounds are useful as antimicrobial agents.
The compounds are prepared in the following several ways. To prepare a 1-arylthio-1,1-dihalomethanesulfonamide, a 1-(arylthio)methanesulfonamide is reacted with chlorine or bromine. The reaction is advantageously carried out in the presence of an appropriate organic solvent, i.e., methylene chloride or carbon tetrachloride as reaction medium. The reaction is carried out at a temperature at which hydrogen halide product of reaction is formed, advantageously at a temperature between about 20°C. and 40°C. The reaction consumes equimolar proportions of the starting materials and such proportions or a small excess of halogen are advantageously used. The reaction is carried out in the presence of pyridine as acid acceptor for the by-product hydrogen halide.
In carrying out the reaction, a solution of halogen in an inert organic solvent such as, for example, carbon tetrachloride, is added to the 1-arylthio-methanesulfonamide and the acid acceptor in an inert solvent, advantageously substantially equimolar proportions of the primary reactants, and the reaction mixture is stirred until the reaction is substantially complete. The progress of the reaction can be monitored by examining the nuclear magnetic resonance spectrum of the reaction mixture. The dihalomethanesulfonamide product in solution in the reaction medium is separated from by-product pyridine hydrohalide salt, the filtrate cooled and the dihalomethanesulfonamide product crystallized therefrom. If necessary, it is recrystallized from an appropriate solvent such as methanol, ethanol or the like.
The corresponding 1-(arylsulfinyl)methanesulfonamide or 1-(arysulfonyl)methanesulfonamide is halogenated with substantially two molar proportions of alkali metal hypohalite, advantageously formed in situ from halogen and aqueous alkali metal hydroxide. Such reaction is advantageously carried out by slurrying the 1-(arylsulfinyl)-or 1-(arylsulfonyl)methanesulfonamide in aqueous alkali metal hydroxide and adding thereto bromine or chlorine, advantageously with stirring and cooling and an ice bath to control the exotherm, then maintaining the reaction until halogenation is substantially complete. It is sometimes advantageous to have dioxane present as co-solvent. The solid product is filtered off and recrystallized, advantageously from methanol or ethanol, to give the corresponding arylsulfinyl-or arylsulfonyl-dihalomethanesulfonamide product.
The following examples additionally describe representative specific embodiments and the best modes contemplated by the inventors of carrying out the invention. Temperature is given in Centigrade degrees. The compounds are identified by elemental analysis and by nuclear magnetic resonance spectroscopy.
